Building block and method for assembling building blocks

A building block, configured as a parallelepiped, comprising:

• three pairs of opposing faces, including four lateral faces and two faces constituting an upper and a lower bases, each of the faces including a plurality of elements constituting projections and recesses, wherein each of the elements is shaped as an equilateral pyramid with rounded edges, and the pyramid vertex angle between two opposing faces is within the range from 90 to 179.9 degrees, the projections and recesses are arranged in rows and columns, wherein the pyramid bases at each of the parallelepiped faces are arranged in a single plane, and the respective sides of the pyramid bases are parallel to the parallelepiped faces, wherein the sides of the bases of the pyramids that constitute the projections are adjacent to the respective sides of adjoining pyramids that constitute the recesses, the rows and columns at the parallelepiped's upper and lower bases being mutually perpendicular to each other, wherein the number of projections in the rows and columns at the parallelepiped's upper and lower bases is not equal to the number of recesses and is an odd number, wherein the sum of the numbers of projections and recesses in the rows is equal to the sum of the numbers of projections and recesses in the columns, such that an alternate arrangement of projections and recesses is provided in the rows and columns at the parallelepiped bases, bases of the pyramids at the parallelepiped's lateral faces in the rows and columns that adjoin the sides of the lateral face being spaced apart from the lateral face edge, to form a flat region of the surface at each of the lateral faces around its periphery, the number of projections in the rows and columns at the parallelepiped's lateral faces being equal to the number of recesses, and their sum in the rows and columns is an even number, such that an alternate arrangement of the projections and recesses is provided in the rows and columns at the lateral faces of the parallelepiped, the building block being configured such that, when any two blocks are coupled with each other at their lateral faces, projections at a lateral face of one of the blocks are engaged with recesses at a lateral face of the other of the blocks, and, when any two blocks are coupled with each other at their bases, projections and recesses at the lower base of one of the blocks are engaged with the respective recesses and projections at the upper base of the other of the blocks, the projections and recesses at the block faces enabling coupling of four blocks, three of which having paired adjacent faces that are perpendicular to each other and in contact at the edges, while a fourth block is coupled with said three blocks along a linear path that passes through the point of junction of the three faces, at an angle to each of said three blocks' lateral faces within the range from 45 to 89.95 angular degrees.

A building block, configured as a parallelepiped, comprising:

• three pairs of opposing faces, including four lateral faces and two faces constituting an upper and a lower bases, at least one of the lateral faces or at least one of the base faces including a plurality of elements constituting projections and recesses, wherein each of the elements is shaped as a regular pyramid with rounded edges, and the pyramid vertex angle between two opposing faces is within the range from 90 to 179.9 degrees, the projections and recesses are arranged in rows and columns;
• wherein the pyramid bases are arranged in a single plane which is a face of the parallelepiped, and the respective sides of the pyramid bases are parallel to the parallelepiped faces;
• wherein the sides of the base of a pyramid that constitutes a projection are adjacent to the respective sides of the bases of adjoining pyramids that constitute the recesses, at least one of the lateral faces including a surface that replicates a construction material texture, the rows and columns at said at least one base of the parallelepiped being perpendicular to each other;
• wherein the number of projections in the rows and columns is not equal to the number of recesses, and their sum is an odd number;
• wherein the sum of the numbers of projections and recesses in the rows is equal to the sum of the numbers of projections and recesses in the columns, such that an alternate arrangement of projections and recesses is provided in the rows and columns at the parallelepiped bases, the building, block being configured such that, when any two blocks are coupled with each other at their lateral faces, projections at a lateral face of one of the blocks are engaged with recesses at a lateral face of the other of the blocks, and, when any two blocks are coupled with each other at their bases, projections and recesses at the lower base of one of the blocks are engaged with the respective recesses and projections at the upper base of the other of the blocks.
